. . . Next time I saw Samantha she said that porkchops were usually a favorite food so she was not sure what the issue was - but no apology, in fact she asked if "We could try it again sometime"

In addition to the family's appalling behavior at the cookout and the lack of an apology, Samantha seems to be angling for another invite from you. You hosted her family. She now needs to reciprocate in some manner. I suspect that in addition to being boors, this is a family of moochers.

It takes two people to play tug of war. If you don't want to play, don't pick up the rope.

OP, you did nothing wrong. When a parent tells me "My kids will eat anything" I take that as it sounds. I have a kid who would have, and still does, eat anything. Only now he cooks it as well. I may have to have him experiment on making the maple vinaigrette. If he figures it out I'll post it to the receipe section.
